If you Google the word "ableism" the first result to come up is: "discrimination in favor of able-bodied people (emphasis added.)"

This is much different from the definition of an other discrimination such as racism or sexism. These are defined as prejudice, discrimination , or antagonism directed against people of said group; feeling as though you are superior to them. Ableist acts are often more passive and most prevalent in our day to day lives.
